For the tower, slice vegetables, cheese, and salami into three-inch lengths. With the exception of the asparagus (unless you have enormous spears), halve, quarter, and/or trim ingredients so they are similar in size.

Place serving dish where you plan to serve it as it will be difficult to move once you've finished. Begin with a solid base that includes three items of equal size with flat bottoms and tops (you may want to do extra trimming on this foundation layer). Continue stacking, alternating items for variety as you progress. Each layer should include at least two vegetables of equivalent size to maintain the stability of the tower. It the tower begins to lean, back track a layer or two and adjust as necessary. Build as high as you dare!

To prepare the dip, combine ingredients in a medium bowl. Mix well to combine. Refrigerate until ready to serve.
